talib.EMA

The talib.EMA() function is used to calculate the Exponential Moving Average.

The return value of the talib.EMA() function is a one-dimensional array. array

talib.EMA(inReal) talib.EMA(inReal, optInTimePeriod)

The inReal parameter is used to specify the K-line data. inReal true {@struct/Record Record} structure arrays, numeric arrays The optInTimePeriod parameter is used to set the period, the default value is 30. optInTimePeriod false number

function main() {
    var records = exchange.GetRecords()
    var ret = talib.EMA(records)
    Log(ret)
}

import talib
def main():
    records = exchange.GetRecords()
    ret = talib.EMA(records.Close)
    Log(ret)

void main() {
    auto records = exchange.GetRecords();
    auto ret = talib.EMA(records);
    Log(ret);
}

The EMA() function is described in the talib library documentation as: EMA(Records[Close],Time Period = 30) = Array(outReal)
